Cormier might be able to in LHW. I'd also give Machida and Gus a real chance. Dodson might and i see Barao getting the real belt too. Those are the only ones I can see changing.
JDS - Keeps his belt Jones - Keeps his belt Silva - Keeps his belt GSP - Loses his belt to Hendricks Bendo - Keeps his belt (Unless Aldo moves up) Aldo - Keeps his belt Cruz - loses to Barao when he comes back Johnson - Keeps his belt Rousey - Keeps her belt
Cain stands a good chance, I still pick JDS but it's like 60-40 Pettis has a good chance if he gets his shot. Cyborg beats Rousey in late 2013. Barao can beat Cruz Jones, Anderson, GSP, Aldo, and Mighty Mouse all win out the year.
Hendricks is Koscheck 2.0, he's not beating GSP. Barao will beat Cruz, but that may not be in 2013 >_>.
